What happens if I make the first 6 month order and decide not to continue the program.

Hi what is the expiry date?

Does it protect against ticks?

I placed an order the other day for advantage multi and need to Know how to divide the doesage into smaller amounts. I have 20+ dogs and buying like this keep them healthy as well as saving "mama" money. I had someone who was going to figure it out and call me back but never happened. I have dose my vet figured out for advantix one time, but not sure if that will be the same as that was Advantix 100. Could someone please figure the dosage out for like dogs 10lbs and under, 11- 20lbs, 21- 54 ect.( that is how they did it for me before at my vet. I also need to change from ordering every 6 months to every 3 months how do I do that? Thank you for you help..Know your are not a vet like I was told by someone there on the phone the other day but will be a better customer if someone could help me with this dosage on the anvantagge multi...Thanks again

I have 170lb great dane would I have to use 2 tubes on him?
